AGMA 2015-1-A01 is a standard that defines the accuracy requirements for spur and helical gears. The standard provides a set of guidelines for gear manufacturers to ensure that their products meet specific tolerances and quality standards. The standard covers various aspects of gear accuracy, including:

While most engineers are familiar with AGMA 2000 (the standard for gear quality), represents a critical evolution in how we define, measure, and classify that geometry. It shifts the focus from the outline of the tooth to the action of the tooth.

The AGMA 2015-1-A01 document typically covers:

"This isn't about stress formulas," Marcus said, confused.
